REFRIGERATING CABINET.

Application liled March 10, 1924. Serial No. 698,030.

Y 10 all whom t may concern Be it known that I, Lnn H. PAYNE, a citizenoi' the United States, residing at Milwaukee, in the county of Milwaukeeand State ot' llliscoiisiii, have invented certain new and usefulImprovements in Refrigerating Cabinets, of which the following is aspecilication.

This invention relates to a cabinet for maintaining at a low temperatureproducts, such as ice cream, and the like, and particularly to arefrigerating cabinet in which ice in subdivided form is packed around acontainer for the goods.

It has heretofore been proposed, tor the purpose of econoinizing in t-heconsumption or' ice, to limit the vertical dimension of the mass of icewhich surrounds the container by excluding the ice from the lowerYportion or' the container-receiving space and using the latter as abrine well, and d ependingon the salty water which develops' from themelting of the ice to keep the lower portion of the container' cool; andthe object ot the present invention is to provide a construction ofrefrigerating cabinet operating upon this principle, but which will beof simpler construction and more eliicient in the cooling capacity ofthe brine well. Accordingly, the present invention proceeds upon theprinciple of having the transverse dimensions of the brine wellsufficiently near to those ot the end of the container, which enters thewell, to adapt the container to serve as the ice excluding element,although suliciently larger than the container to develop an elicientbrine circulating space around the inner end of the container; but thisbrine circulating space is of such restricted capacity that thecontained liquid cooling medium, namely, the brine, will circulatetherein and be replaced by cooler' liquid from the ice pack as fast asthe imbalance in temperature develops, and thus not only is the ice eX-cluded from the brine well without the complication of specialpartitioning means, gratings, and the like,but the brine is preventedroin accumulating around the inner end of the container in any suchvolume as would admit of local circulation and interference withreplacement of brine from the melting ice. Means are introduced betweenthe inner end of the container and the walls of the brine well formaintaining distance ot' all the walls of the two members, and thusinsuring continuity of the brine well entirely around the container; andthese spacing means extend beneath the container so as to prevent itresting on the bottom of the well as well as at the sides thereof, as,

for instance, by developing the spacing means in the form of strapsextending along vertical walls ol the container and having deflectedends that enter beneath the container.

In the accompanying drawing`- Figure l shows, in vertical section, arelirigerating cabinet embodying the several features of the presentinvention.

Figure 2 is a horizontal section on the line QX-X of Figure l; and

Figure 3 is a detail view, in perspective, showing one of the straps forspacing the container in the Well.

l represents a refrigerating cabinet constructed with inner wall 2,outer Wall 3, and heat insulating material 4 between said walls, and 5represents a container for goods to be kept cool by means of a packing 6ot' ice surrounding the container. According to the present invention,the interior space of the cabinet l, in which the container 5 isreceived, is subdivided into an ice chamber 7 which, while completelysurrounding the container 5, is nevertheless terminated short ot thelower end ot the container, and said lower end is accommodated in abrine well 8. Vhile that portion of the inner wall 2 of the cabinetwhich develops the ice chamber 7 is spaced a considerable distance fromthe container 5 in order to admit the substantial mass ot ice, therelative transverse dimensions ot the brine well 8 and the lower end ofthe container 5 are suoli as to leave a Space between these members thatis too small to admit of pieces of ice although sufficient to permitbrine,which naturally settles from the ice pack, to substantiallysurround the container and insure cooling of the lower end thereof.

In order to uniformly space the lower end of the container from thewalls of the brine well 8, straps 9 are symmetrically distributed insaid' space, preferably at the corners, when the opposed walls of thecontainer and well constitute the sides of a polygon, and these strapshave their ends 10 deflected-beneath the bottom of the container 5 sothat they keep the latter from resting upon the bottom ol the well S,and excluding brine from the bottom space.

I claim l. In a refrigerat-ing cabinet, an ice-receiving chamber, abrine well at the inner end of and of less transverse dimension thansaid chamber7 and a container extending trom the chamber into said welland of a dimension which leaves between the container and the walls ofthe well a space that will not admit ott ice but which is sutlioient topermit brine from the ice chamber to circulate therethrough; means beingprovided in the brine well Ytor spacing the walls o't the container andbrine well at intervals? and maintaining the brine space around thecontainer.

ln a retrigerating cabinet, an ice-receiving chamber a brine wellat theinner end,

of and of less transverse dimension than said chan'iber, and a containerextending from the chamber into said well and ot a dimension whichleaves between the container and the walls of the well a space that willnot admit; oit icev butK which is su'tticient to permit brine from t-heice chan'iber to .circulate therethrough; means being provided in thebrine Well for spacing the walls et the container and brine well atintervals. and maintaining the brine space around the container; saidmeans being located beneath the endas wellas at the sides ot thecontainer.

Inr a refrigerating cabinet, an ice-receiving chamber, abrine well atthe inner end of and of less transverse dimension than said chamber, anda container extending from the chamber into said well and ot a dimensionwhich leaves between the container and the walls ofthe Well a space thatwill 'not admit o-tice but which is sulicient to permit brine from `theice chamber to circulate therethrough; means being` provided forspacing` the walls of the container and brine well at intervals, andmaintaining the brine space around the container; said means comprisingstraps distributed at intervals around the container.

et. In a` refrigerating cabinet, an ice-receiving chamber, a brine wellat the inner end ot and of less transverse dimension than said chamber,and a container extending trom the chamber into said Well and of adimension which leaves between the container and the walls oit the wella space that will not admit ot ice but which is sutiicient to permitbrine from the ice chamber to cir culate therethrough; means beingprovided for spacing the walls of the container and brine well atintervals, and maintaining the brine space around the container; saidmeans comprising straps distributed at intervals aroundlthe container,and i having their ends deliected beneath the container and supportingthe container above the bottom ot the brine well. l

ln a retrigerating cabinet, an ice-receiving chamber, a brine well atythe inner lend ot and ot' less transverse dimension than said chamber,and a container extending trom the chamber into said well and of adimension which f leaves between the container and the walls oft' thewell a space that will not admit o tL ice but which is sui'iicient vtopermit brine trom' the ice chamber to circalate therethrough; meansbeingprovided within the brine well for spacing the walls ot thecontainer and brine wellat intervals, and maintaining the brine spacearound the container; the brine well "being of polygonal transversesection1v and the spacing means being located at the corners of thepolygon.
